About this site
Secret Bay is a muck diving site in Anilao, Batangas, on the Philippine island of Luzon, an area well known among divers for macro life along its volcanic sand and silt slopes. The site reaches a maximum depth of around 18 metres and is rated a beginner dive. Anilao's sheltered bays are a popular base for macro-focused diving in the region, making Secret Bay part of a broader network of muck sites there, and its shallow depth and easy conditions make it approachable for divers still building experience.
